Install your drives top down. You may have to format them. See pages 16 thru 29 for the various flavors of windows. Power on the device. press the RAID button, on the back of the box for three seconds until the led flashes. Press it again, select the raid mode you want (the first light of the series on the front of the box ) press THE CONFIRM BUTTTON ON THE REAR PANEL OF THE BOX until the box powers down. Power the device on again and the raid mode is setup. (Read the instructions page 6 and refer to page 1 "OVERVIEW" for the front panel light/button descriptions. If this doesn't work let me know. I have for 4ea 1tb drives configured as raid 10 (Mirrored pairs). But only one drive letter on my computer. Install your drives top down. You may have to format them.

Should not be a problem. upon powering up, push the raid button to your desired array, then hold the button in the back until it re-boots.

Make sure that you are confirming your choice of RAID setup with the RAID button located on the back of the unit. From the user manual:First install the HDD from up to down in the enclosure. Power on device. Press RAID button for 3 seconds until LED flashes. Press it again, select the RAID mode you want to use and press the RAID Mode Confirmation Button on the rear panel until the device shuts down. Power the device on again. RAID mode setup is now complete.

You can fill as few as 2 slots (using one drive as a redundant drive) and leave the rest open for later use. I initially loaded 6 slots with drives and allowed the NAS to test all 6 drives. I them removed 2 drives and keep them as backups. I now have 4 3TB drives installed and running just fine configured as one volume.

you would have 18 bays, * 4TB drives for a potential of 72TB of space.... HOWEVER - actual space will depend on the RAID mode you choose and the security and peformance you desire. Also a formatted 4TB doesnt really give you 4TB so you will probably have 3.2-3.6 TB from each drive. The real issue IMHO is the quality of 4TB drives and the performance. Unless you dont care about your data I wouldnt create a single volume that big.

I'm not sure either. I've only used mine for 1 drive. I doubt it would work for 2 at once. You would probably need 2 adapters and some software that could reconstruct the data, which is shared between the 2 raid 0 drives.

The drives must be the same size and yes you can put only 4 drives in the NAS. In order to configure as a RAID 5 though you will need at least three drives. I used 5 drives and configured 4 of them as RAID5 leaving the 5th drive as a "hot spare".

All of the drives are combined into one drive. There are no options to create two logical disk drives.

No. Once you do the initial setup, if you add a second drive you can not set it up to run in Raid 1 without having to format the drive.

It's either/or. When you set the drive up you have the choice of using the RAID 1 or 0 configuration. If you decide to change your mind later, you'll end up losing everything you've stored on the drive. I stuck with the RAID 1 config to provide redundancy, even though it cut the capacity by half.

Two 4TB drives. You can configure it to mirror those two 4TB, split it so parts if each file could end up on both drives (makes it very fast, but vunerable to corruption if either one fails), or separately to use them as two unique 4 TB drives for a total of 8TB.

I am about to install a 6TB drive so I will let you know if I am successful but according to intel, it should be fine. The support of your HDD depends on the RAID card. This is a RAID expander and is only meant to extend an existing RAID controllers capacity of HDDs. This does not create a RAID array.UPDATE: I have installed my 6TB WD Red HDD and have no issues. Simply plugged it in, turned on my server, and it showed up in my OS (Linux Mint 17.1) without any issues. No configuration needed. Just plug and play.

I have 8 of these NAS drives in a non-RAID case. They are all setup as individual drives. I move them from one computer to the next with no problems.

You can configure the drive to be either 4 TB or 8 TB. The device itself only contains two 4TB drives.

Their is no problem with mixing various size drives. I did that until I eventually updated to all 4th drives.

Update-I did have to put in 5 old, dummy drives to setup the Raid 5 on the new box & then put in my 5 drives, in order of course, & the Raid came right back up. I just happened to have 5 old drives to use. Otherwise, I don't think you can do it any other way.

It's best to get this NAS it's own set of drives. The point of this NAS is to RAID the drives to protect against failures, swapping drives won't work as you'll just be constantly rebuilding the array. I suppose you could just have 1 drive and move it back and forth between two of these NAS units, but what would be the point there?

My two WD Green 2TB drives worked until one failed. The two WD Red 4-TB drive does not work in DNS-321, failed to format and could not recognize the correct capacity in the RAID 1 configuration menu. FW is v1.03.
